Patented Sept. 24, 1907.

To all 'whom 'it may concern:

Be it known that CHARLES HENRY MYERS, a citizen ofthe United States, residing at Buffalo, in the county of Erie and State of New York, has invented a new and useful Wrench-Socket, of which the following is aspecification.

The use of ratchet wrenches in railway track Work has heretofore been impracticable, so far as 1 am aware. The reason for this has been that the bases or lower outstanding flanges of the splice-bars are located so very close to the' paths of movement of the corners of the nuts that no ordinary wrench head, whether straight faced or beveled can revolve when applied to such nuts. The ordinary wrench is therefore employed, and it has to be applied to a nut four times in order to effect a single complete rotation of such nut. .At the saine time, the nuts are ordinarily screwed home with great forcepand being exposed to the action of the elements, become rusted and held in place, so that great power is ordinarily required to loosen and remove them.

The present invention has for its principal object the provision of a wrench head that can be readily applied toa track nut, can be completely rotated with the same and without the necessity of removing it from the nut, and is of suflicient strength to withstand, without breakage, the strain necessarily incident to its use.

In the `accompanying drawing .-Figure l is a side elevation of a'wrench having the improved head forming a part of the same. Fig. 2 is a side elevation of said head removed. Fig. 3 is an end elevation of the head. Fig. 4 is a sectional view on the line 4-4 of Fig. 3.

y Fig. 5 is a view in elevation of a portion of a splice-bar and nut, and showing the `close relation existing between the paths of movement of the corners of such nut and the outstanding flange of the splice-bar. Fig. 6 is a sectional view through the same. Fig. 7 is a similar view, illustrating the wrench head in position thereon.

Similar reference numerals designate corresponding parts in all the figures of the drawing.

In the embodiment illustrated, a stock 8 is employed having at one end, a rotatable head circular in cross section operated by any suitable or desirable ratchet mechanism, which need not here be specifically set forth. In the embodiment shown, a tapering shank 9 is employed that is angular in cross section, and extends transversely of the stock. One end of the shank carries the head 10, which, as shown in Fig. l, is located at one side of the stock and tapers on all sides towards its outer or free end. A nut-receiving socket 1l opens through the outer side 'of the head,` and a boltreceiving bore 12 communicates with the inner end of the socket, and extends entirely through the shank. The outer annular face 13 of the head is circular, and is curved from the inner side of the head to the outer side having the socket. This face intersects the corners of the socket, and thus inwardly extending notches 14 are formed at said corners, and through the annular face 13. The opposite end of the shank to that carrying the head 10 is reduced and preferably threaded, as shown at l5. Screwed thereupon is a nut 16, constituting the means for retaining the shank in place. Instead of this nut, any suitable fastening device may bel employed.

In Figs. 5, 6 and 7, a portion of a track structure is illustrated, one of the splice-bars being shown at 17, and having an outstanding base portion or flange 18, which is located at an angle to the outstanding portion, as clearly shown in Figs. 6 and 7. The tie-boltrl9 has screwed upon one end, the usual nut 20, and the corners of this nut, as will be apparent, operate very close to the outstanding flange 18.. The wrench head disclosed in the drawing is readily applicable to a n ut of this character, for said head being disposed on one side of the stock, may be placed upon the nut without interference, and the space thereof will substantially correspond to the space between the nut and the outstanding flange. Moreover, by having the annular wall curved and intersecting the corners of the socket, the head may be fitted properly over the nut and up to its inner side. At the same time, the walls of said socket, except at the corners, are very thick, as shown in Fig. 4 to withstand the strain necessarily imposed thereupon, and even vat these corners, as shown in Fig. 7, a considerable amount of metal is still retained, acting in the nature of webs that connect the sides. The head, moreover, being circular, vcan freely rotate with the nut, and consequently the ratchet mechanism may be employed. At the same time by forming the recesses 14, not only can a perfectly formed nut be turned, but these also may be operated in which the openings are offset from the center.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further'description, and it will'` be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent, is'.-

l. A wrench comprising a stock and a head rotatably mounted on the s tock and having a nut-receiving socket in its front face, said head being circular in cross section and having its outer annular face continuously curved from its rear side to its front side, thereby eliminating corners to said head, securing sufficient metalen all sides of the socket to prevent the walls of said head breaking under strain, ,and permitting the rotation of the head in confined places.

2. A wrench comprising a stock and a head having a under strain, and permitting the rotation of the hond in shank journaled in the stock, said head having flat rear l confined places.

and front faces, a nut-receiving socket opening through its front face, said head being furthermore circular in 5 cross section and having its outer annular face curved I In testimony, that I claim the foregoingas my own, 1 have hereto aixed my signature in the presence of two A witnesses. from its rear to its front side and intersecting the corners y y of the socket, such intersection terminating short of the CHARLES HENI humm' bottom of the socket, the contour of the head thereby Witnesses: eliminating corners, securing sulcient metal on al1 sides C.
